Hello. Following up on this thread, sshd-session was not utilizing libwrap or libblocklist at all after the ssh-9.9 merge. Based on suggested patches from Greg Woods, I committed fixes to sshd-session.c so that it now checks host_access privileges for both "sshd" and "sshd-session" rules in /etc/hosts.* files. This has been tested on a number of amd64 systems. As Greg suggested, I also committed comments to doc/3RDPARTY so folks will know that access control is now in sshd-sessionn and not sshd itself.
Thank you Greg for the bulk of the fix. -Brian
